1. What are the characteristics of a good structure for photovoltaic panels?
A good structure for photovoltaic panels must be stable, durable and resistant to weather conditions such as wind, rain or snow. It is also crucial to precisely position the panels at the right angle to maximize the efficiency of energy production. The structure should be easy to install and adapted to the specifics of the installation site.
2. How have photovoltaic designs changed over the past few years?
In recent years, photovoltaic structures have evolved in terms of strength and ease of installation. Initially, photovoltaic structures were created from aluminum profiles. At this point, designers are outdoing themselves to meet the demands of investors. In order to minimize installation costs and speed up installation, more and more new solutions are being developed both in aluminum and steel. Among them are push-in clamps and one-key bolted systems. Increasing emphasis is also being placed on the aesthetics of the installation and integration with the environment.
3. What are photovoltaic structures made of these days?
Today, the most common materials are: aluminum, which is lightweight, corrosion-resistant and often chosen for its aesthetics. galvanized steel, which is characterized by corrosion resistance thanks to a special layer of zinc; Magnelis-coated steel, which offers high resistance to weathering and mechanical damage thanks to an innovative coating
4. What are the main types of photovoltaic structures?
Structures differ mainly because of the purpose for installation. We have structures for pitched roofs, flat roofs, ground structures, carports, facade or balcony systems. In addition, they can be divided by the method of installation. In the case of roof structures, these will be invasive, ballasted or glued structures. Another important criterion is how the structure is installed in the ground. We can distinguish between several methods: caulking, which involves embedding the panels in the ground with hammers or a piling rig, ensuring that they are firmly in place; anchoring, where the structure is attached with anchors to concrete slabs, ensuring its stability; and concreting, where structures are embedded in concrete foundations, ensuring high stability and resistance to external forces.
5. What is the process of designing, attesting and manufacturing such a photovoltaic structure?
The process of designing a photovoltaic structure begins with an analysis of the site conditions and determining the optimal positioning of the panels. Based on the information gathered, the components of the structure are designed, which must meet construction standards and safety requirements. The next stage is attestation, i.e. obtaining certificates confirming the quality of component materials and the structure’s compliance with standards and norms.
6. What is the lifetime of photovoltaic structures and is subsequent servicing needed?
The lifespan of photovoltaic structures depends on the material from which they are made. Usually it is 10 years with the possibility of extending it to as much as 25 years after appropriate testing at the investment site. Periodic technical inspections are recommended. In the first year after installation, it is recommended to perform an inspection once every six months, and then annually. Check that screws do not loosen and make sure the structure has not suffered mechanical damage or corrosion, especially in areas exposed to harsh weather conditions.
